Vertical lines appearing on LCD screen is very common. Whether the screen belongs to a laptop computer or desktop PC, mobile phone, or even a television, the fault is usually due to the ribbon cable and its connections.

A faulty ribbon cable can cause all sorts of havoc manifesting in bright vertical lines. Sometimes they can be coloured lines such as blue, green, grey, black, and red. The lines can appear thick or thin and on just one-half of the screen. Sometimes the fault will manifest as two vertical white lines. You can even get horizontal lines as well.

If you have lines appearing on the LCD screen, then the first simple thing to check is the seating of the ribbon cable that connects the display panel to the motherboard. Most of the time, the fault is with the poor connection made by the ribbon cable.

One of the most common problems with ribbon cables is oxidation of the contacts. It can happen either on the ribbon cable contacts or on the socket contacts. Manufacturers often use a mix of gold and copper for the electrical contacts, however, if they have not used enough gold, then oxidation occurs over time. This results in a working television or laptop screen suddenly exhibiting lines.

One of the most common faults with laptops is that the ribbon cable connecting to the LCD panel cracks. It typically fails near the hinge area due to flexing in that region, and over time, some of the tracks on the plastic cable breaks. I have seen these types of faults on many laptops. It does not matter whether it is a Lenovo, IBM, Acer, Samsung, Toshiba, or even a MacBook Pro!

This type of fault can also occur on LCD televisions; however, it tends to be on new units, where the box has received an impact during transit from the factory.

In this situation, the repair can be easy, as the cable will simply require reseating. However, there is still the labour time to consider as it can take the best part of the day to gain access to the ribbon cable.

I used this same method of troubleshooting to repair an LCD television recently. Modern televisions have a video out socket, and if you feed the signal from that to another monitor, you can check for the quality of the video display. If the external monitor does not show lines, then you know for sure that it is a connection issue. Hence, this method of troubleshooting works for some of the modern televisions as well.

When half of the vertical interlace is missing showing a picture that is broken up vertically, the display appears with vertical lines. This is usually due to a cracked ribbon cable.

Generally, for laptops a replacement cable is always required due to it breaking near the hinge. I had this Dell laptop and replacing the LCD ribbon cable solved the problem. I managed to buy a replacement from Dell for a modest price £6.00. The laptop was just outside the warranty period; however, they still shipped out the cable free of charge. This is the reason why people buy Dell. In my experience Dell tend to stand by their customers and products, and their prices for replacement parts are realistic and down to earth.

Watching your mobile screen with those white or black vertical/horizontal lines is annoying. In short, it’s tough to use a phone with these lines appearing on the screen.

For example, it could signal that the power supply is either failing or faulty. In other cases, it could mean you have not connected the HDMI cable well, or there is a poor connection between the processing board and the panel. But another cause could be the picture does not fit the screen exactly.

When you see black vertical lines on your TV screen, the first step is to identify the primary cause of the problem. Start by testing the picture, check your cable connections, and verify that your external devices are working well.

You can also try changing channels to determine whether the lines appear on all channels. Understand that lines on a TV screen can either be a hardware or software issue.

Ideally, aspect ratio, screen resolution, and horizontal or vertical scan frequencies are settings that affect picture display on most TVs. In this case, refer to the external device’s user manual to adjust the picture format settings.

Your TV software runs the device. An outdated software program can cause many problems like vertical lines, poor picture quality, or failure to install apps.

In some cases, a TV fails to process a combination of image settings you have provided. That can cause many picture errors, including flickering lines on TV. While you can go through all the settings one by one, consider resetting your device.

Sometimes vertical lines on an LCD display could mean a damaged T-Con board. The T-Con or timing control card controls the timing of pixels displayed on the screen. If your T-Con board is faulty, the only solution is to repair or replace it.

If you see Samsung TV vertical black lines on the screen, check whether the lines are permanent or moving. If they are moving, your input source is incorrect. Disconnect and reconnect the video cable or HDMI to check if it resolves the issue.

Thirdly, you may come across a problem with your Samsung Smart TV whereby colored lines appear on the edge of your TV screen. The lines may be black, white, or green along the top, bottom, or side of the screen.

The issue occurs when you have set the picture size of your TV to JustScan or Screen Fit. Samsung calls the lines an Overscan line. If your setting is JustScan, the picture resolution of specific programs will not fill the screen, thus causing the lines.

You can resolve the issue by setting the picture size on your Samsung TV to 16:9. The setting will extend the picture beyond the edges and eliminate the Overscan line.

You can fix a TV screen with lines in different ways. For example, you can change channels to see if the lines appear on all changes, change the input source, check cable connections, or power-cycle your device.

Power down the computer and unplug all peripherals. If you are using a laptop, take its battery out by flipping it upside down and sliding the battery release latch. Press and hold the power button for 15 or 20 seconds to clear all residual power from the system. Some of the computer’s power might have been transmitting to the monitor, causing it to short out. Reconnect everything and turn the system back on to see if the lines are gone.

Unplug the monitor from the back of the computer and wait a few seconds until it displays a message “No signal.” If the no signal message also has vertical lines, you know the problem is in the monitor and not in your computer. Press the “Menu” button on the screen and then use the other buttons to browse for a “Factory Settings” mode. Select this mode to reset the monitor to its original settings. If the lines persist, the monitor may have been dropped or exposed to a magnet -- which can’t be fixed.

Reconnect and turn the computer back on. Look for the lines at boot up: if you see lines before Windows loads, the problem is either with the video card, the video connection cable -- whether HDMI or VGA -- or the monitor itself. If the lines only appear in Windows, the problem is a Windows setting -- most likely the refresh rate. Right-click on the Desktop once Windows loads and choose “Screen Resolution.” Click “Advanced Settings,” “Monitor,” and then lower the refresh rate to see if the lines disappear.

Whether they"re red, green, or blue, vertical lines on a computer monitor aren"t a good sign. Although it could mean your monitor is getting old and may soon need a replacement, it may just be you have a faulty HDMI or DisplayPort cable. Alternatively, it may be your graphics drivers need updating, or you need to restart your monitor or PC.

Vertical lines on a monitor are one of three core problems: the display panel itself is defective, the connection between your computer and the display is faulty, or it"s receiving erroneous information.

There isn"t much you can do about the former unless your monitor is within its warranty period, but the others have some relatively easy fixes which might get rid of the vertical lines on your computer screen.

The first step to getting rid of vertical lines on your monitor is to see if it"s to do with the display itself or some other issue. Open your monitor"s menu system and see if the vertical lines show up even over the top of the menu screen.

If your monitor"s menu isn"t in the right place to test whether the lines are on the screen or to do with the connection, you can also unplug the monitor and see if the lines are still present when it is powered on without anything connected to the display.

The exact cause of the vertical lines on your computer screen will only be apparent if and when you fix it, so it"s best to start trying these examples to see what works.

Update your graphics drivers. If your graphics drivers are outdated, there may be a compatibility issue causing the vertical lines. Update your graphics drivers to see if it resolves the issue.

Try the monitor on another PC. If you can, test the monitor on a different PC. If the lines are still present, the monitor or the cables are to blame and need replacing. However, if you"ve tried all of the above and the lines aren"t there, you may have a problem with your PC itself.

Horizontal lines may indicate overheating, physical damage, or a screen resolution issue. To fix the issue, check the monitor connection and resolution, and remove any magnets nearby. Also, turn the monitor on and off, restart the computer, and connect your computer to a different monitor to test it.

To fix ghosting (screen burn) on a monitor, try shutting down the monitor and leaving it off for 48 hours. Another option: Use an all-white screensaver and let it run on your display for several hours. You can also try a software tool that fixes stuck pixels, such as JScreenFix.

LCD display screens on notebooks, monitors and TVs alike are made up of two thin layers of glass containing liquid crystal material between them. When the glass becomes damaged, debris infiltrates the crystal layer or another issue occurs with the display function, this causes vertical lines of color to appear when the monitor is fully illuminated. These lines are either permanent due to internal failure or temporary due to faulty display connections.

Diagonal, jagged and both horizontal and vertical lines typically indicate panel damage. A single set of horizontal lines could indicate damage, a graphics system failure, or loose internal video cables. Broken signals from cables or graphics hardware creates impurities in reproducing an image on an LCD screen, conditions that often manifest in the form of vertical or horizontal lines of color.

If the lines are infrequent in their appearance, or are not permanently visible, a loose video cable is often the problem. As devices are carried, dropped and bumped, cables become loose even in laptops. Laptops are built with casing to absorb and dissipate small shocks, but even some bumps can cause cables to become loose. Even televisions and monitors, while often stationary, can still have loose cables if not properly seated.

If you"ve ever opened your laptop to clean underneath the keyboard, you might see numerous things like food particles, hair or even dust. On the rear of monitors and televisions, they also contain a series of holes or slits that dust can creep into the inner workings and cause problems. Regularly cleaning out a laptop"s keyboard and dusting off the rear of a monitor or television can greatly extend its useful life. This is a preventative measure and rarely works in removing any existing lines on a screen.

The first step in troubleshooting is determining the extent of the damage. For external monitors or televisions, re-seat any video input cables or consider replacing the cables with new ones. Should the lines continue to display, this indicates an internal failure, something few consumers are able to fix on their own. Instructions exist online for individual products to disassemble a monitor, laptop or television to replace broken parts, but the most suggested course of action is shipping it to the manufacturer for a warranty repair. If no warranty is active for the device, consumers are then advised to replace the device entirely with a new one, as this is usually the cheapest solution. Lines on an LCD panel indicate the LCD screen or screen ribbon cable need to be replaced, parts that can cost several hundred dollars.
